This blockv 'is provided 'with a transversef slot 24' leading fromr the' upper endtherfeof and an opening 25i'leailing from the upper .end f orentrance ofthecord 113. Adjacent its innerend'thishlock isf-provided with a 'female' {ih-read" 26ft0" receiye -tihe externally thread-ed vprojection v27mm'riecl by the het lindric'e'l Vi'langeQS 'to project; into the ripper end :of fthef insert" 29" and jtr -Whichf lit -is connected byi--any-[suitaple ni'eans, such' es screws 3cr-f The pbloolz, alsofp:1'e*tiere-lillyy hesa fange 31 to form `a stop shoulder for the upper end of the insert and to give a finished appearance. The insert flares outwardly at its loWer end, as shoivn at 32, and is overlapped with the upper end of the shade or casing lll to Which it is secured by suitable means, such screws 33. This insert is also provided With a series of upright slots 3d for enit of cooling air.

At its upper end the block 23 is provided With cars 35 through which extend clamping screws 36 by Which the opposite sides of the block may be clamped against the cord 13 to relieve the connection of the lead Wires to the contacts in the socket 11 of the Weight of the lamp and reflector.V

lt is at times desirable that the lamp should be used in an inclined position in order to project the rays atan angle to the vertical, as when it is desired to project the rays to the side of' a patient. To allori7 for this l have provided bosses 37 on opposite sides of the block 23 and mount thereon a pivoted holding device 38. rl`his device is preferably made of a flat strip 4of metal bent to substantially U-shape With the opposite sides 39 embracing the block and bearing against the bosses 3T, and passing through these arms and the block is a bolt L10 with a thumb nutel. This provides a pivotal connection between the holding element and the block, and also provides means for clamping the element to the bloclr in difterent positions. rllhe remainder of the holding device is shaped so 'as to lie closely adjacent the outer surface of the casing le when not in use as shown in Fig. 1. By loosening the nut Zl1 the holding device may be swung about its pivot to any position desired and then clamped therein by means of the thumb nut. The method of using this device to hold the lamp in an inclined position is shown in Fig. 5. The holder is swung so that the cord 13 Will rest in the seat formed in rthe free end of the holder by the connection Ll2 joining the sides and Where the holder is clamped in this position it will react with the cord to hold the lamp inclined, as shown inFig. 5.

lt will be apparentV from the foregoing Vdescription that `Jthe mounting and reflector for the lamp are very simple in construction involving a small number of parts which may be quickly'and easily assembled and disassembled. The three sections of the reflector, ll, 23 and 29 may be easily disconnected by removing` the screws 30 and @33. I consider my improved means of mounting the lamp socket 11 Within the reflector also ofnnportance. By providing a "female thread 26 in the block 23 and provid ingar'i externally'threaded projection 27 on the socket it Will be obvious the socket may be easily screwed Vinv position or unserewed therefrom, and that these operations may be performed Without in any Way disassembling the reflector'. r:this construction is also cheaper to manufacture.

From an inspection of Fig. 3 it will be seen that, as the bolt l0 passes transversely through the passage for the cord 13, this cord is bent laterally to one side of the bolt, and this bend coacts with the bolt to provide an additional means of taking part of the strain of the Weight of the lamp and reflector from the connections of the lead Wires to the contacts in the socket.

It Will also be apparent that when the lamp and` reflector are held in an inclinedposition there can be no pocket for dead air formed at the juncture ofthe reliector 16 and the member le, the notches 21 allowing any air Which might collect in this pocket to pass through and to the exit slots 22. Thus there is always floiv of cooling air over the inner surface of members 14 and 16, preventing any overheating.

Having thus set forth the nature of my invention, what l claim is:

1. In a therapy lamp, a dome shaped casing enclosing the lamp and open at its top and bottom, a tubular insert connected with the casingat its top and forming a continuation thereof and provided With air exit openings in its side Walls, a block secured to the other end of the insert and provided With a longitudinal passage, a socket for the lamp carried by the block Within the insert, lead Wires extending through said passage to the socket, and an inner dome shaped reflector enclosing the lamp Within the casing and mounted above theV bottom ofthe casing, said reiiector being provided with an air outlet opening at the top thereof about the lamp and outwardly extending projections at the lower end thereof to space it from the casing and allow cooling air to flow over the inner surface of said casing.

2. ln a. therapy lamp, a shade or casing enclosing the lamp, a one piece block to Which the shade is connected havinga transverse slot extendingV from its outer end, a lamp Vsocket carried by the block, said block having a longitudinal opening therethrough, lead Wires extending through said opening to the socket, and means for clamping the slit portion of the bloclrto the lead Wires.

3. ln a therapy lamp, a one piece block iaving a longitudinal opening extending therethrough and provided with a transverse slot leading from the outer end thereof, alamp soc zet secured to the inner end of the block, lead Wires passing through the block from the outer end to the socket, and means for clamping the opposite sides of the slit portion of the block against the lead Wires.

l. in a therapy la1np,`a block having a longitudinal passage extending therethrough and having side Walls providing clamping PotlO-HS.: ai rttorsecured :to bleek,

said block being provided with a female thread, a socket enclosed by the reflector having lamp contacts and provided with an externally threaded projection adapted for engagement with the threads of the block, lead wires extending through said block to the socketl and means for clamping said clamping port-ions to the lead wires.

In a therapy lamp, a block, a reflector secured to the block, a lamp within the re`r Hector, lead wires extending through the block to the lamp, a holding device having spaced side elements str addling and pivoted to the block and adapted to swing on its pivotto and from engagement with the lead wires and adapted t0 coact therewith to hold the lamp and reflector in an inclined position, and means for securing the holding device in adjusted positions.

8. In a therapy lamp, a. block having a lon gitudinal passage, a reflector carried by the block, a` lamp socket carried by the block within the reflector and having lamp contacts, lead wires extending through the passage to the socket and connected with the contacts, a holding device pivot'ed to the block, said pivot comprising a bolt extending transversely through the passage in the block lin position to cause the lead wires to bend laterally, and means for clamping the holding device in adjusted positions, said device adapted to swing to and from engagement with the lead wires and to coact therewith to hold the lamp and reflector in in clined positions.

9. In a therapy lamp, a block, a reflector carried by the block, a lamp enclosed bythe reflector, lead wires extending through the block t0 supply current for the lamp, a sulo' stantially Ushaped holding device arranged with the side members thereof em-y bracing the block, a pivot bolt extending through the side members and the block, and a nut on the bolt for clamping the device in adjusted positions, the portion of the device connecting the side members adapted to engage a side of the lead wires and coact therewith to hold the lamp and reflector in inclined positions.

In testimony whereof I affix my signa- Y ture.
